NASA's Juno Captures Rare View of Jupiter's Moon Amalthea

The elusive moon was photographed transiting the Great Red Spot, revealing new mysteries about its composition and behavior.

  • Amalthea, Jupiter's fifth-largest moon, was spotted by Juno during its 59th close flyby on March 7, 2024.
  • The moon appeared as a small dot against the backdrop of Jupiter's Great Red Spot, a massive storm.
  • Amalthea is irregularly shaped and is the reddest object in the solar system, possibly due to sulfur from Io.
  • The moon emits more heat than it receives from the sun, likely due to Jupiter's magnetic field and tidal stresses.
  • Citizen scientist Gerald Eichstädt processed the images, which are available for public exploration on NASA's website.
